TPS650864: Buck2 to 0.9V

Part Number: TPS650864

Tool/software:

Hi team,

Customer has been used TPS6508641RSKR for 0.85V core. However, they wants to try different FPGA, so want to change Buck2 to 0.9V. Is it ok as sequence? Which registers does it need to be written?

REgards,

Hayashi

  • Hi Hayashi-san,

    Please ask the customer to write data 0x32 (0.9V) to register 0x21 (BUCK2CTRL).

    If Buck2 need to have same voltage in sleep mode as well (if it is enabled in sleep mode), they have to write the same value to register 0x93 (BUCK2SLPCTRL) as well.
